' V SNAP'EGAJUGE.

I Application filed September 14, 1926.: SerialN o. 1135.448.

.Tl1is invention relatesfltoj gauges and particular to an outside dimensional gauge aves app a iu 't saev sob'e't of thepre'sent vention is to provide improved adjustingmeans for an anvilofa gauge adapting the anvilto be positively. Q adjusted in Qpposite directions relative to the. gaugejframe. i; Anotherobjiect of tfheinvent on s to provide screwthreaded means for adjusting the fright F and, left hand One'feature which H the right and left threaded'jmemberengages internal threaded portions formed respectively in the frame and anvil.

Another object otthe invention is to provide improved" rotatable cam locking means for the anvil enabling the anvil to be locked in any adjusted position.

With the above and other objects in view my invention consists in the features of construction and operation set forth in the following specification and illustrated in the accompanying drawing. In the accompanying drawing annexed hereto and forming a part of this specifica' tion, I have shown my invention embodied in a snap gauge having a single pair of opposed adjustable anvils but it will be understood that the invention can be otherwise embodied and that the drawing is not to be construed as defining or limiting the scope of the invention, the claims appended to this specification being relied upon for that purpose.

In the drawing:

Figure 11s a side view of a complete snap gauge having the improved anvil adjusting and locking means, one side of the frame being sectioned to more clearly show the invention.

Fig. 2 is a sectional view taken upon the line 22 of Fig. 1.

Fig. 3 is a separate view of the oppositely thpleaded adjusting member for the anvil, an

Fig. 4 is a separate view, on an enlarged scale, of the rotatable cam locking member for the anvil.

In the above mentioned drawing I have shown but one embodiment of the invention which is now deemed preferable, but it is to be understood that changes and modificaanther. aflgauge having threaded portions is advantageous is that tioijis as be made-- within the sco e bi the] appended claims without departing from the spirit of the invention.

Briefly, and infits broadest'aspect, m invention comprises the [followingprincipal parts} first, a frame substantiallyof U form; second, "anvils adjustably positioned within the frame and movable toward'or from each other; third, a member having oppositely threaded portions. adapted to engage internal threads formed respectively in the frame and anvil; and fourth, arotatablecam member disposed transversely to the anvil and adapted to clamp the anvilin any adjusted Position. I Referring more indetailto thefiguresof' ie;dmwi s gauge emb dying th invem tionis shown having a frame lObfU form of any desired distance between the arms. At the ends of the arms of the frame 10 are mounted anvils 11 preferably having heads 12 at their inner ends. The anvils 11 are in alignment with each other and one or both may be provided with the improved adjusting and locking means. As shown in Figs. 1 and 2 the anvils 11 are adapted to slide within cylindrical openings in the frame 10; I p

In orderto adjust an anvil 11 it is provided with internal threads 13 extending axially of the' anvil. In engagement with these threads 13 are threads 14 on the smaller diameter portion of the adjusting member 15. The larger diameter portion of this member 15 is provided withthreads 16 adapted to engage threads 17 formed internally in the cylindrical opening in the frame 10 for the anvil 11. The threaded portions 14 and 16 on the adjusting member 15 are of opposite hand. It will be seen therefore that rotation in one direction of this member 15 will positively move the anvil 11 in one direction and rotation of the member 15 in the opposite direction will oppositely move the anvil 11. To rotate the member 15 its outer end is slotted as shown at 18.

The clamping means for the anvil 11 com prises a rotatable member 19 freely rotatable within a transverse opening in the frame 10" intersecting the opening for the anvil 11. At the ends of this member 19 are cylindrical portions 20 adapted to engage the walls of the transverse opening within which member 19 the surface is cam or spirally shaped, as shown at 21, so that by rotating the member 19 this surface canbe brought into contact with a plane surface 22 formed along one side of the anvil 11. To rotate the clamping member 19 one end may be slotted as indicated at 23.

From the above description it will be "seen that by rotation of the adjusting member 15 the position of the anvil 11 relative to the frame 10 may be positively adjusted in either direction. Also that when the anvil 11 has been adjusted to the desired position it may beclamped in fixed position by means of the clamping member 19. As the cam member 19 is at all times closely adjacent the fiattened portion 22 of the anvil 11 the anvil is prevented from rotating while being adjusted longitudinally.

What I claim is: v

1. A snap gauge comprising in combination, a framehavin internal threads formed therein, an anvil s idably mounted therein having internal threaded portions, an adjusting member positioned Within the frame and having threaded portions of opposite hand engaging respectively the internally threadedportions in the frame and in the anvil,

and means to lock the anvil in any adjusted position. v

2. A snap gauge comprising in combination, a frame, an anvil slidably mounted therein, an adjusting member positioned within the frame and disposed in alignment with the anvil, threaded portions on said adnally threaded portions on said frame and H anvil adapted respectively to engage the threaded portions of'said adjusting member, and rotatable cam meansto'lock the anvil in any axial adjusted position;

In testimony whereof, I *hereto aflix my signature.
